Grafting is a surgical procedure to move tissue from one site to another on the body, or from another creature, without bringing its own blood supply with it. Instead, a new blood supply grows in after it is placed. Different types of grafting contains  skin grafting, bone grafting, vascular grafting and ligament repair. Skin grafting is most common used grafting technique. Wounds, burns and scars have been dealt with this efficiently. Bone transplantation is a bit difficult but well-known process to replace damaged bones. In Recent years cardiovascular disease are being combatted with the development of a tissue-engineered vascular graft (TEVG). The various approaches to generate TEVGs are scaffold-based methods and tissue self-assembly processes. The channels for vascular grafting are autologous arteries or veins. Synthetic vascular grafts are also available in the market nowadays.

Aging is the successive or dynamic change in a living being that prompts  to an increased risk of debility, disease, and death. Skin loses its juvenile luster with age. Permanent pimples, wrinkles and texture irregularities are very common. With advent of cosmetic surgery this can be reversed. The process is generally based on layer by layer removal of the surface cells and the new cells are thus formed.

Cancer is the most dreaded disorder. The exact cause and mechanism is yet not known. Diverse research is going on find an answer. Tissue engineering has been inter-related with cancer to find some ways. Using tissue engineering to comprehend cancer can be done by fabricating 3D constructs that will mimic tumor cells and help us know how cancer cell grow, spread and metastasize at the biological level.
